T0 all whom, it m/cty con/cern.'

Beit known that I, JosEPH S. PARROTT, a citizen of the United States,residing at Cass City, in the county of Tuscola and State of Michigan,have invented certain new and useful Improvements in Milk-Coolers; and Ido declare the following to be a full, clear, and exact description ofthe invention, such as will enable others skilled in the art to which itappertains to make and use the same.

My invention relates to milk-coolers; and one of the objects of the sameis to provide a device of simple construction which will quickly andthoroughly cool the milk and separate the cream therefrom.

Another object is to provide a milk-cooler and cream-separator whichwill present the milk in a comparatively thin stream or film to aninterior Water-jacket or inner tubular Water-container in order that themilk may be quickly cooled and the cream readily separated therefrom.

These and other objects are attained by means of the constructionillustrated in the accompanying drawings, in which- Figure l is a sideview of a milk-cooler made in accordance with my invention. Fig. 2 is acentral vertical section of the same. Fig. 3 is a perspective View ofthe Water-container or inner receptacle. Fig. 4 is a similar view of themilk-receptacle. Fig. 5 is a perspective view of the inner or waterreceptacle and the outer or milk receptacle surrounding saidWater-receptacle..l Fig. 6 is a perspective view of the c over for thewaterreceptacle and showing the water-agitator or plunger passingthrough said cover. Fig. 7 is a detail section showing a modified formof the inner and outer receptacles.

Referring to the drawings for a more particular description of myinvention, the numeral l designates the inner or cold-water receptacleprovided with a cover 2, having a central opening 3 therein, and asuitable agitator or stirrer 4:, passing through the opening 3 andprovided with a suitable handle and with a number of arms or dashers 6.The milk-receiver 7 has an enlarged upper end 8 and an inclined bottomportion 9 and a tubular extension lO, which is slightly larger than thediameter of the water-receptacle l. Any suitable receptacle ll may beemployed t0 receive the milk after it has been cooled by the devicereferred to.

The operation of my invention is as follows: The water-container lhaving been iilled with cold water is inserted in the opening l0 in themilk-receptacle 7. These parts are then placed in position upon anysuitable can or receptacle for receiving the milk. The milk to be cooledis then poured into the receiver 7 and surrounds the water-casing l andin a comparatively thin stream or film trickles down around thecold-Water casing l into the milk-receptacle 11. The stirrer or agitatoris operated to present cold water around the inner wall of thewater-receptacle l and to agitate the water from the bottom to the topin order that the milk may be quickly cooled and the cream separatedtherefrom.

A suitable cock l2 may be employed for removing the milk and cream, and,if desired, a sight-opening 13 may be utilized for indicating the heightof the milk and cream in the milk-container or outer receptacle.

From the foregoing it will be obvious that my invention is simple inconstruction, can be produced at slight cost, is eiicient for itspurpose, andwill cool the milk in a very short time, owing to the factthat the milk is presented in a comparatively thin stream or film to theouter wall of a cold-water jacket or receptacle.

As shown in Fig. 7, the inner `receptacle l and the outer receptacle llXmay have conical bottoms a and o, and a cock c may be attached at theapex of said outer receptacle, thus serving to permit the milk to bequickly Withdrawn from the cream.

Various changes in the form, proportions, and minor details ofconstruction may be resorted to without departing from the principle orsacrificing any of the advantages of the invention.

Having thus described my invention, what I claim, and desire to secureby Letters Patent, is-v l A cream-separator or milk-coolercompristension adapted to lie closely against the Water-container,substantially as described. IO

In testimony whereof I have hereunto set my ing; a milk-receptacle acylindrical Water-container adapted to be placed Within themilkl'eceptacle to contain cold water, a verticallyniovable agitator orplunger-rod provided hand in presence of tWo subscribing Witnesses. 5with arms o1' dasliers Within the Water-container, a milk-receiversurrounding the Wa- Witnesses:
